苦榄岩






大洋岩，一种苦榄岩


苦榄岩是一种火成岩，镁含量较高，主要由橄榄石和辉石组成，橄榄石要大于30%，辉石少于40%，有时含有一些长石，但要少于10%。含有橄榄石比例大的苦榄岩由于颜色发绿色和蓝色，也被称为“大洋石”。


苦榄岩是一种喷出岩，有粒状结构，含有钛，可以形成钛铁矿、磁铁矿和磷灰石等。


夏威夷岛的基拉韦厄火山喷出的岩浆会形成大洋岩，其他火山在火山口中也会形成大洋岩[1]。


大洋岩的名称首先是由拉克罗瓦提出的，是用在橄榄石超过50%的苦榄岩，主要指夏威夷岛[2]和留尼旺岛[3]的火山喷出岩。





应用


苦榄岩由于其高耐火性能，高熔化温度，可以应用于翻砂铸造和制造耐火材料。

Volkswagen Group MQB platform

Image
The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. Volkswagen spent roughly $60bn [1] developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB , which stands for Modularer Querbaukasten , translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". [2] [3] MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes th...
